Transcriptomics and Deep Sequencing Core


Due to high demand and low staff, RUSH options will not be available through the remainder of the year as we are unable to process samples in a properly expedited fashion.  We apologize for any inconvenience.



Effective December 1, 2020, the Core is excited to announce reduced costs on most NovaSeq runs!  Sequence more for less!  Combine our new lower NovaSeq prices with new lower Single Cell library prep costs and take advantage of huge discounts.



Effective 10/6/2020, new lower prices for single-cell sequencing allows our customers to process more and save more!  Receive bulk discounts on as few as TWO samples!


6/10/20 NEW COVID-19 Update:


Effective Monday, June 15, the Transcriptomics Core will re-open!  In accordance with University policy, we will observe all social distancing requirements.  To ensure the safety of our clients and lab members, APPOINTMENTS ARE REQUIRED FOR SAMPLE SUBMISSION.  iLabs submission is required before scheduling an appointment.


Please go to the Schedule Equipment tab to reserve a time slot for sample submission.





Pricing update:

Effective 1/1/2020, the monthly usage charge for Ingenuity Pathway Analysis will increase to $300.  The hourly charge for computer usage will increase to $30/hour.



Overview of Services

Our aim is to provide cost-effective and time-efficient access to cutting-edge genomic technologies and expert assistance with experimental design and data analysis. The Core has been in continuous operation since 2002 and has supported research projects for more than 467 principal investigators, 1097 individual researchers, and processed more than 36,000 samples (as tallied in April 2016). We offer sample preparation and analysis using Next Generation & Third Generation sequencing technologies, Microarrays, Nanostring nCounter, and qPCR.  We also offer high throughput DNA, Chromatin, and RNA shearing using the Covaris E220 system. Our lab is equipped with both PacBio and Oxford Nanopore platforms for third generation, long read, single-molecule real-time (SMRT) sequencing, as well as the Illumina NextSeq 500, MiSeq, and iSeq next-generation sequencer for short reads. We work closely with the ECGC to enable our clients access to the Illumina HiSeq 2500/3000 and NovaSeq for deeper sequencing requirements. The third-generation long-read sequencing technologies are great for genome assembly, novel transcript isoform identification, full-length 16s rRNA gene sequencing for metagenomics, repeat sequences, and GC-rich region targeted resequencing, as well as for bacterial DNA methylation study.  The Illumina short-read sequencing technology, with its high throughput, is great for whole-genome resequencing, whole-exome sequencing, RNAseq, ChIPseq, 16s rRNA gene, or whole-genome metagenomic sequencing, and targeted DNA resequencing.  We run the Affymetrix microarray system while offering preparation and support for Agilent arrays as well. In addition, we offer the Nanostring nCounter system for RNA expression, FFPE analysis, CNV, and miRNA detection. We ensure a full-service experience for our clients, starting with project design, all the way through publication. We encourage our clients to meet with us before beginning any projects to ensure the most accurate and efficient results. From nucleic acid extraction through analysis, we are your one-stop-shop.
